A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

Step 1: Convert the child's weight from pounds to kilograms.

44 pounds / 2.2 pounds/kg = 20 kg

Step 2: Calculate the child's total daily dose of gentamicin.

20 kg * 6 mg/kg/day = 120 mg/day

Step 3: Divide the child's total daily dose of gentamicin by the number of doses per day.

120 mg / 3 doses/day = 40 mg/dose

Step 4: Calculate the volume of gentamicin to be administered with each dose.

40 mg / 40 mg/mL = 1 mL/dose

Step 5: Round the answer to the nearest whole number and add a leading zero if necessary.

1 mL/dose = 1 mL/dose

Answer: 1 mL with each dose.

Correct Answer is D

Explanation

Choice A rationale:

While reminding the client to change positions slowly is important to prevent orthostatic hypotension, it is not the priority before administering furosemide.

Choice B rationale:

Preparing the client’s medication is an important step, but it should be done after reviewing the client’s electrolyte levels.

Choice C rationale:

Recording the client’s urinary output is important when administering furosemide, a diuretic, but it is not the priority action.

Choice D rationale:

Reviewing the client’s electrolyte levels is crucial before administering furosemide because it can cause electrolyte imbalances, including low potassium levels, which can lead to serious cardiac complications.

A. Dissolve the medication in 30 mL of water. B. Maintain the client in the supine position during medication administration. C. Add the medication to the enteral feeding formula. D. Flush the tube with 5 mL of water after administering the medication.

Correct Answer is A

Explanation

Choice A rationale:

Dissolving the medication in 30 mL of water is the correct action. This ensures that the medication is in a suitable form for administration via an NG tube and helps prevent the tube from becoming blocked.

Choice B rationale:

Maintaining the client in the supine position during medication administration is not recommended. This position increases the risk of aspiration. Instead, the client should be in an upright position during medication administration and for at least 30 minutes afterward.

Choice C rationale:

Adding the medication to the enteral feeding formula is not recommended. This can alter the effectiveness of the medication and can also clog the feeding tube.

Choice D rationale:

Flushing the tube with 5 mL of water after administering the medication is not enough. The tube should be flushed with at least 15-30 mL of water before and after medication administration to ensure that the entire dose has been administered and to prevent clogging of the tube.
